About
- History:
- 2009-07-09 moved to separate wiki page; no design changes
- 2011-11-23 added WhenEnt, WhenUpd
- Notes:
- (2011-11-23) Possibly WhenUpd should be removed and replaced with one or both of:
- WhenCnf (when confirmed) -- stamp whenever a new order is received that contains this email
- WhenEdt (when edited) -- stamp whenever an admin saves the record
- same for cust_phones and cust_emails
- (2011-11-23) Possibly WhenUpd should be removed and replaced with one or both of:
SQL
CREATE TABLE `cust_names` (
`ID` INT NOT NULL AUTO_INCREMENT,
`WhenEnt` DATETIME NOT NULL COMMENT "date when record was first created",
`WhenUpd` DATETIME DEFAULT NULL COMMENT "date when record was last updated",
`ID_Cust` INT COMMENT "core_custs.ID",
`Name` VARCHAR(127) COMMENT "customer's name, for shipping label",
`NameSrch` VARCHAR(127) COMMENT "name with delimiters removed, for matching",
`isActive` BOOL DEFAULT FALSE COMMENT "NO=wrong spelling or name; use for searching",
PRIMARY KEY(`ID`)
)

Utility
SQL query to get a list of cust records with multiple names:
SELECT
g.*, n.Name
FROM
(SELECT
c.ID, COUNT(n.ID) AS NameCount, GROUP_CONCAT(n.ID) AS NameIDs
FROM
cust_names AS n
LEFT JOIN cust AS c ON n.ID_Cust = c.ID
GROUP BY c.ID
HAVING COUNT(n.ID) > 1) AS g
LEFT JOIN
cust_names AS n ON g.ID = n.ID_Cust
WHERE
n.ID IS NOT NULL
ORDER BY g.ID
